public final class ISO8601Util
extends Object

Copyright (c) 2017, Jackson Authors/Contributers. Utilities methods for manipulating dates in iso8601 format. This is much much faster and GC friendly than using SimpleDateFormat so highly suitable if you (un)serialize lots of date objects. Supported parse format: [yyyy-MM-dd|yyyyMMdd][T(hh:mm[:ss[.sss]]|hhmm[ss[.sss]])]?[Z|[+-]hh[:]mm]]
